  • Xcode developer package: Xcode is found on the Mac App store. Install command line tools through the XCode preferences and/or running in a terminal xcode-select --install



  • CMake (version >= 16.3)
  • Microsoft Visual C++ (ROOT6 requires at least Visual Studio 2019 version 16.1). The Community version is free, fully-featured for students, open-source contributors, and individuals.
  • Python (ROOT6 requires version >= 2.7)


ROOT 6 on Windows is currently in beta, and has several known issues as well as missing features. We are currently working on making ROOT on Windows production-grade.

ROOT 5 (deprecated)

If you are using Windows make sure you have installed Microsoft Visual C++ (e.g., the no-cost edition) plus CMake. The CMake build will work directly without the need to install cygwin as it was required previously before the adaption of CMake.
